It's starting to get pretty hot here in DC and after a reasonably long ride the radiator fan on the left side of my 2017 GTS 300 kicks on and is crazy loud. It has a startling whine sound to it and starts pushing out some serious hot air. I imagine pushing hot air out is a good thing, but I'm pretty sure it isn't supposed to sound like this. I've got about 1,000 miles on this thing and got it last summer. It happened once last year, but didn't repeat, so I kinda forgot about it.
Any advice on how to fix it? Or should I take it to get serviced?
